KNIFE-BLADE LEATHER-PUNCH.

Specification of Letters Patent.

Patented Oct. 16, 1906.

Application filed April 6, 1906. Serial No. 310.294.

To all whom it may concern:

Be it known that I, SEYMOUR LANDON AL- VORD, a citizen of the UnitedStates of America, residing at Winsted, in the county of Litchfield andState of Connecticut, have invented certain new and useful Improvementsin Knife-Blade Leather-Punches, of which the following is aspecification.

The object of the invention is to provide a device of the classspecified having features of novelty and advantage.

Figure 1 is a front view of a blade embodying my invention. Fig. 2 is anedge view thereof. Fig. 3 is a sectional view on the line 3 3 of Fig. 2.Fig. 4 is a view of the back of the blade. Fig. 5 is a view of a knifewith the blade closed into the handle.

Referring to the drawings, the blade is shown in general at (1, having asubstantially flat face I) and curved rear side 0 and a flat roundedpoint d. The blade is provided with a longitudinal cutting edge e, whichis raised slightly above the plane of the flat face of the blade. Therounded point is preferably sharpened on its front and back edges.

By following out my invention it is possible to forge the blade, and theshape of the blade is such that it can be ground and finished on itsfront and rear sides. By providing a blade with the flat roundedsharpened point it begins to cut as soon as it is applied to the leatheror whatever material it is to be used on and can be forced through theleather or other material with very slight exertion. The blade closesinto the knife-handle exactly as the regular knife-blades, the sharpenedpoint -and cutting edge being protected and the blade when closed intothe knife presenting the appearance of the ordinary blade.

claim as my invention 1. An article of the character describedcomprising a blade having a substantially flat face, a curved rear side,a longitudinal cutting edge upstanding slightly above the plane of theflat face and a rounded and sharpened end.

2. An article of the character described comprising the blade having asubstantially flat face, a curved rear side, a longitudinal cutting edgeupstanding slightly above the plane of the flat face, and a double-edgedend, substantially as described.

3. The combination with a pocket-knife handle,of a leather-punchbladepivoted thereto, said blade having a flat face and curved rear side, adouble-edged end, and a cuttingflange starting at the point and in theplane of the flat face of said blade and extending along the inner edgeof and toward the base of said blade and upstanding above the flat facethereof and gradually increasing in height from the flat point to thebase.

4. An article of the character described comprising a blade having asubstantially flat face curved rear side and a cutting edge starting atthe haft and extending along the inner side of said blade and around therounded end thereof, said cutting edge being upturned along the inneredge of the blade to form a cutting-flange Which stands above the planeof the flat face of the blade, substantially as described and for thepurposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.
